Abstract

CHEHARDOLI, Gholamabbas et al. [H₂-cryptand 222]²⁺(Br₃^-)₂ as a tribromide-type catalyst for the trimethylsilylation/tetrahydropyranylation of alcohols. S.Afr.j.chem. (Online) [online]. 2011, vol.64, pp.127-131. ISSN 1996-840X.

A stable organic tribromide, [H₂-cryptand 222]²⁺(Br₃-)₂ was utilized as an active catalyst for the trimethylsilylation/ tetrahydropyranylation of alcohols. The method is general for the preparation of OH-protected aliphatic (acyclic and cyclic), aromatic, primary, secondary and tertiary alcohols.

Keywords : H₂-cryptand 222]²⁺(Br₃-)₂; trimethylsilylation; tetrahydropyranylation; alcohols; tribromide; TMS-ether; THP-ether.
